Rutta (undisclosed) left Saturday's contest versus the Capitals in the second period, Tom Gulitti of NHL.com reports.
EDGE Analysis
It's unclear how Rutta was hurt, but he didn't play after the 7:26 mark of the second period. With the Lightning also seeing Nikita Kucherov (undisclosed) exit in the third period, they may be forced to make some call-ups from AHL Syracuse ahead of Tuesday's game versus the Panthers. More information on Rutta should be available the next time the Lightning practice.
